Total glucose CV was 39.91% (95% CI: 39.20, 40.61) in the insulin glargine U-300 group, compared to 41.22% (95% CI: 40.49, 41.95) in the insulin degludec U-100 group (mean difference: 5.44% [95% CI: -6.50, -4.38]

How Topical GHK-Cu Works Topical copper peptides act locally on the skin to: Stimulate fibroblasts Increase collagen and elastin production Improve skin thickness and texture Support the skin barrier Benefits of Topical Copper Peptides Non-invasive and easy to use Lower systemic exposure (especially in individuals with elevated or high-normal copper levels) Ideal for long-term skin maintenance Helpful for fine lines, wrinkles, tone, and texture Well-suited for prevention and early intervention Limitations Localized effects only Results are gradual and require consistent use Best For Patients focused on skin longevity and appearance Preventative or maintenance care Those who prefer non-injectable options Injectable Copper Peptides (GHK-Cu) Injectable GHK-Cu delivers copper peptides systemically , meaning effects extend beyond the skin
